We like to think we can spot a rebodied Pontiac Fiero when we see one, but we have to admit that this Concept 2000 GT eBay find had us scratching our heads for a bit. According to our research, this unusual car isn't one of two General Motors prototypes produced, as the seller claims, nor is it a prototype Ford, as indicated by a couple images included in the ad. It's actually one of a dozen or so cars built in the 1980s based on the Fiero.
